APPLICATION FILED OCT. 25. 1916- Pa tented Mar. 20, 1917.

Inns 2?. WRIGHT,

To all whom it may meme- 1 'Be it known that I, P. WRIGHT, a 1hzen ofthe United States, residing at \Vashin'gt 'on,- in the. District ofColumbia, have invented certain new and useful Improve ments'inPressure-Roll Releases for Clothes- Wringers, of which the following isa specification,' reference being had therein to the accompanyingdrawing.

' This invention relates to certain new and useful improvements in apressure roll; release for a clothes w'ring'er, the object being i to"provide a release in which a resilient retaining member is employedcodperating wi'tli non rotatable sliding boxes mounted in the top bar ofthe wringer frame in such a manner that by bowing the resilient member'the' same can be contracted in order to move'theendsthereof out ofengagement of the slidably mounted boxes so as to allow the boxes tomove vertically with the pressure screws carried thereby in order torelease the pressure on the pressure rolls.

Another object of my invention is to provide the threaded boxeswith'beveled por-- tions adapted to engage the free ends of theresilientmember when forced into position within-the wringer frame so asto allow the boxes to be reset after they have been released.

Another and further object of the invention is'to, provide a clotheswringer with sliding boxes so constructed that'they are prevented fromrotating within the bearing sleeves and are provided with means forlimiting the upward movement in order to pre- I vent the boxes fromjumping out of the frame when the pressure is released.

'Other and further objects and advantages of the invention will behereinafter set forth and the novel features thereof defined by theappended claims.

'In' the drawings,

Figure 1 is a side elevation partly in section of a clothes wringershowing the application of my improved construction of pressure rollrelease thereto; and

Fig. 2 is a perspective view of a threaded box and bearing detached.

Like numerals of reference refer to like parts in the several figures ofthe drawing.

In the drawing I have shown a wringer slotted side bars 2 carrying arigid top bar mnITEDiFs AT-ns mama nail OF WASHINGTON, DISTRICT OFCOLU1VIBIA,'ASSIGNOR TO JOHN FRANCIS HEMENWAY, OF NEW YORK, N. Y. I

3 which is preferably secured within the slotted portions of the'sidebars by a transversely extending bolt or pin.

Mounted within the slotted side bars are superposed bearings carryingpressure roll shafts 4 and having the usual rubber pressure rolls 6 and7, and provided with meshing gears inclosed by gear casings as clearlySpecification of I ietters latent. patg tefl Ri 2Q j gi g Applicationfiled October 26, 1916. Serial No. 127,397 i style ofwringer now in use,and I have shown this particular form of pressure means, but I do notwish to'limit myself to any particular construction of pressure meansfor exerting the pressure on the pres sure rolls.

A vertical bore is formed in each end of the top bar 3 into which isdriven a slightly tapered bearing sleeve 12, said sleeve being insertedfrom the under side of the bar so that the same will be held within thebore of the top bar by a wedging action so as to prevent the sleeve frommoving vertically within the top bar after it has been placed inposition it of course, being understood that the bore of the sleeve iscylindrical throughout its length, and that the outer surface is onlyslightly tapered. The sleeve is provided with oppositely disposed offsetportions forming grooves 13 adapted to re ceive the oppositely disposedribs 14 of an internally threaded cylindrical box 15 when said box isplaced in position in the bearing sleeve so as to allow the box tosli-deeasily within the bearing for the purpose hereinafter fully described.

The bearing sleeve 12 is provided with a notch 16 into which extends alug 17 formed on the lower end of the box 15 so as to limit the upwardmovement of the box with n the bearing sleeve when, said, boxisreleased.

The box 15 has a greater length than the bearing sleeve 12 and isprovided with a notch 18 adapted to receive the adjacent end portion ofa fiat spring 19 which is slidably' mounted in guideways 20 on the underside of the top bar 3, said. spring having acentral bowed portion 21which is engaged by the head 22 formed on the lower end of the shank 23of a push button 24 which is slidably'mounted within a vertical boreformed riedby the top bar of the wringer frame in order to hold theboxes rigidly within the bearing sleeves so that the pressure screws 24mounted within the boxes can be adjusted so as to exert the properpressure on the pressure rolls through themedium of the pressuresprings, bearing plates and pressure bar as the pressure screws arebrought into engagement with the bearing plates as they are screwedthrough the boxes w as to force the plates downwardly in ordertocompress the springs. When the push button 2a is forced downwardly thespring 19 is contracted so as to draw the free ends from out of thenotches 18 of the boxes 15 which allows the boxes to move vertically apredetermined distance within the bearing sleeves 12 so as toinstantaneously release the pressure on the pressure rolls. I

In order to provide means for resetting therelease after it has beenoperated, I form the threaded boxes 15 with beveled portions 25 at theirlower ends, adapted to engage the free ends of the spring 19 when forceddownwardly into the boxes so as to force the free ends of the springinwardly in order to allow the spring to expand into the notches 18 soas to lock the boxes in position within the bearing sleeves in such amanner that the pressure screws can be rotated to adjust the pressuremeans.

From the foregoing description it will be seen that'I have provided aclothes wringer with a frame having pressure rolls and pressure meansfor said rolls in connection with the movably mounted non-rotating boxescarrying pressure screws for adjusting the pressure means which are heldin predetermined position by the resilient member so that when theresilient member is contracted through the medium of the push button theboxes will be released in order to release th pressure means.
